I am trying to build a prototype of a patent I will be filing. I am looking for design engineer to develop plans or calculate the specifics that a CNC machinist would need in order to build it. It is a gasoline engine simpler than a one-cylinder internal combustion engine. You would be required to calculate intake and exhaust port sizes and a few other lengths for optimal performance. You would also need to be able choose the correct materials for the project. A confidentiality agreement would need to be signed and mailed to me. I think this is a fairly simple project. If you are interested send a message with an estimate for what you think it would cost to design plans for a one-cylinder engine and/or any questions you would need to know in order to figure out your estimate. At this point, I will not be spending more than 5,000 on this project. But, if your estimate is less than 15,000, you might submit it and I will get back to you in the future when I have some more money saved up. And, if my budget is well below what a mechanical engineer would make for this, maybe you would know a college student who has the skills to do this and would want to do it and send them this way. Thanks for your interest and any advice you have.
